Big Data History

E-commerce, in particular, has exploded data management challenges along three
dimensions: volumes, velocity and variety.

On Volume: 
The lower cost of e-channels enables and enterprise to offer its goods or services to more
individuals or trading partners, and up to 10x the quantity of data about an individual
transaction may be collected—thereby increasing the overall volume of data to be
managed.

On Velocity:
E-commerce has also increased point-of-interaction (POI) speed, and consequently the
pace data used to support interactions and generated by interactions

On Variety: 
Through 2003/04, no greater barrier to effective data management will exist than the
variety of incompatible data formats, non-aligned data structures, and inconsistent data
semantics.
